    With CGMS (Continuous Glucose Monitoring Systems):

    "A continuous glucose monitoring system (CGMS) is an FDA-approved device that records blood sugar levels throughout the day and night. There are a number of technologies that are being tested but the only approved device -- Medtronic's MiniMed device -- can provide up to 288 glucose measurements every 24 hours. The system is used to measure an average blood sugar for up to 3 days, while the person with diabetes continues daily activities at home."

    There are glucose receptors located in the brain, the liver, the intestines and the pancreas. All interact to maintain glucose homeostasis. But the most direct control mechanism is carried out by the pancreas via a negative feedback loop. The pancreas responds to low levels of glucose by releasing the hormone, glucagon, which causes glycogen stored in the liver to be transformed into glucose. When the glycogen stores are depleted, fats and then proteins are transformed into glucose. When there is excess blood glucose, insulin is released from the pancreas which allows glucose to enter the cells. If there is more glucose than the cells need, then it is stored in the liver as glycogen via a process called glycogenesis. The other glucoreceptors are involved in initiating feeding behavior.

    Good question! The answer is, by a negative feedback loop (basically when the body reacts to counteract a change induced). So, the level of glucose in your blood normally is called your fasting glucose (without addition of food). When you eat, the levels of glucose in your blood spikes. In a normal person, this triggers the beta cells in your pancreas to secrete insulin, (won't go into too much detail here), which basically brings the levels of glucose back down. If your blood glucose is too low alpha cells in the pancreas are triggered to secrete more glucagon which brings blood sugar levels back up.

    In a diabetic, depending on whether you have type one or two, you either can't produce insulin or it doesn't work the way it should. This means you can't bring your blood glucose levels back down, which is why you may need to take insulin directly to stimulate this process.

    The brain does this job perfectly fine, until it is overriden by Gluttony.
